Department of Medicine Faculty Papers

BACKGROUND: Heart failure (HF) remains a major cause of mortality and hospitalization despite advances in guideline-directed medical therapy (GDMT). Electronic health record (EHR)-based clinical decision support tools may improve care delivery, but their impact on outcomes remains ill-defined.

PROJECT RATIONALE: As part of a system-wide HF quality improvement initiative, we evaluated 2 EHR interventions: an evidence-based HF admission order set promoting early diuresis and GDMT optimization, and a templated HF documentation tool (HFNOTE) designed to capture clinical complexity.

PROJECT SUMMARY: We analyzed 4,865 HF hospitalizations across 10 hospitals between December 2024 and June 2025. Overall risk-adjusted mortality index was 0.83 …

Rural/Urban Disparities In Utilization Of Diabetes Self-Management Training (Dsmt) To The Fee-For-Service Medicare Population, 2017–2024, Wanying Zhu, Aleksandr Taraskin, Jeffrerey Talbert

Rural & Underserved Health Research Center Publications

Key Report Highlights

• A significant rural DSMT access gap exists. Rural beneficiaries accounted for 20.1% of Medicare beneficiaries with diabetes but only 7.8% of DSMT participants.

• Geographic availability remains limited. Only 16.8% of counties with DSMT utilization were rural.

• Access, not demand, appears to be the primary challenge. Rural counties offering DSMT achieved utilization rates more than twice those observed in urban counties (6.0% vs. 2.5%).

• Expanding rural DSMT capacity may represent a high-impact opportunity to improve diabetes self-management support among underserved Medicare beneficiaries.

Cost-Effectiveness Evaluation Of Artificial Intelligence-Assisted Chest Radiograph Interpretation For Tuberculosis Screening In Rural Health Units In The Philippines, Harold Henrison C. Chiu, Bryan Christopher C. Lao, Gloanne C. Adolor

Graduate School of Business Publications

Background: Tuberculosis remains a major public health burden in the Philippines, where diagnostic delays are amplified by limited radiology capacity in rural health units (RHUs) and geographically isolated and disadvantaged areas (GIDAs). Computer-aided diagnosis (CAD) using artificial intelligence (AI)-assisted chest radiograph interpretation may shorten the screening pathway and reduce reliance on scarce specialist readers. However, its economic value for RHUbased tuberculosis screening has not been fully evaluated.
Methods: We developed a decision-tree cost-effectiveness model in Microsoft Excel 365 to compare AI-assisted chest radiograph interpretation with conventional manual radiologist or teleradiology interpretation among a theoretical annual cohort of 1,000 presumptive tuberculosis …

Rural & Underserved Health Research Center Publications

Overview of Key Findings

• Rural counties have higher per capita numbers of substance use disorder treatment facilities than urban counties on average, but also greater variability and large pockets of unmet need.

• The highest proportions of residents living in counties without any treatment facilities are concentrated in rural areas within the Midwestern and Southern United States.

• Rural and urban treatment facilities offer medications for opioid use disorder (MOUD) at similar rates, with inpatient facilities most likely to provide MOUD, followed by residential and outpatient settings.

Comments Re: Regulation For Federal Financial Assistance, Fred D. Ledley, Edward Zhou, Brian C. Fox

CISI Publication

This comment focuses on the proposed modifications to §200.205 “Federal Agency Merit Review of Proposals” and §200.340 “Termination and suspension” of Title 2 of the Code of Federal Regulations. We argue that the pre-issuance review, discretionary termination provisions, and other constraints of federal research support that would be established under this proposal create impediments to the scientifically-driven process of discovery and innovation that has long provided the foundation for advances in American prosperity, influence, health, and wellbeing. Our comments focus specifically on federal support for biomedical research by the National Institutes of Health (NIH) for the purpose of advancing healthcare …

Using United States Medicare Program Claims To Identify Reliable Measures Of Low Value Services Influenced By Primary Care Physician Decisions, Chris Fleming, Dmitriy Poznyak, Rhea E. Powell, Claire Erba, Eunhae Shin, Rui Wang, Claire Burkhart, Arkadipta Ghosh, Eugene C. Rich

Division of Internal Medicine Faculty Papers & Presentations

BACKGROUND: Low-value services (LVS) are those that “… provide little to no benefit to patients….”¹ Among an existing set of 31 LVS are invasive procedures not typically performed by primary care physicians (PCPs), and other LVS that may be commonly provided by specialists. To facilitate research on the role of primary care physicians in low-value care, we sought to identify the reliability of two subsets of LVS measures that are more directly subject to PCPs’ decisions. We refer to these as primary care adjacent (“PCA”) LVS measures.

METHODS: Retrospective observational cohort study to identify which of a 31-item LVS …

From Evidence To Action: Case For Further Investment In Family Planning For Faster Fertility Decline, Population Council Pakistan

Sexual and Reproductive Health, Rights, and Choices

For over three decades, the Population Council Pakistan has generated evidence and supported governments in designing innovative approaches to address population and reproductive health challenges. Building on evidence around fertility transition, reproductive health, and the nationally endorsed Tawazun (balance) narrative, the Population Council supported the Government of Punjab through the FCDO-funded Delivering Accelerated Family Planning in Pakistan (DAFPAK) initiative and other strategic partnerships to implement scalable solutions for strengthening family planning services. This brief outlines five high-impact, proven interventions ready for institutional scale-up and provides an actionable path forward to transform routine health encounters into sustainable health system reforms.

Voucher Model For Family Planning: Empowering Poor Women And Expanding Access To Family Planning Services In Punjab, Population Council Pakistan

Sexual and Reproductive Health, Rights, and Choices

Pakistan continues to face significant inequalities in access to family planning (FP) services, with the poorest women bearing a disproportionate burden of unmet need. Financial constraints, transportation costs, limited mobility, restricted decision-making power, and inadequate access to quality services often prevent women from obtaining the family planning services they need.

To address these barriers, the Population Council, in partnership with the Benazir Income Support Programme (BISP) and the Punjab Population Innovation Fund (PPIF), designed and rigorously evaluated an innovative Family Planning Voucher Scheme.

The model linked social protection with reproductive health services, enabling poor women from Rahim Yar Khan (RYK) …

Johansson, Moritz U. G. Kraemer, Eyal Leshem, Francesca F. Norman, Alfonso J. Rodríguez-Morales, Henrik Salje, Stephen Thomas, Scott C. Weaver, Lindsey A. Laytner, Rebecca Sturgis, Suzanne K. Scheele, Davidson H. Hamer

Pharmacy Faculty Articles and Research

Chikungunya, a debilitating mosquito-borne disease caused by chikungunya virus, has surged dramatically in the past two decades. Chikungunya outbreaks can intensify rapidly, with infections posing a significant endemic health burden in tropical/subtropical areas and for travelers. Health professionals require timely and accurate outbreak information to adequately protect travelers and assess chikungunya risk. However, detection is often insufficient in the areas most susceptible to outbreaks, leading to diagnostic and reporting delays. Consequently, travelers are often unaware of increased chikungunya infection risk at their destination. We assessed chikungunya surveillance and reporting resources, and we developed expert recommendations for traveler health protection. Because …

A 7-year-old girl presented with a 10-day history of generalized purpura and petechiae. The eruption began with a solitary violaceous macule on the trunk and progressed within 1 week to multiple oval and round dark-red to violaceous purpuric macules, ecchymoses, and petechiae affecting the face, trunk, and extremities. Lesions were distributed parallel to skin cleavage lines with a characteristic “Christmas-tree” pattern on the back (Fig 1). No oropharyngeal lesions were noted on examination, and the patient denied sore throat or oral discomfort. She reported no pruritus, pain, fever, or systemic symptoms.

Partial Versus Full Revision In Cementless Single-Stage Exchange For Hip Periprosthetic Joint Infection: A Multicenter Comparative Study With 10-Year Survivorship Analysis, Wenbo Mu, Atthakorn Jarusriwanna, Boyong Xu, Scot A. Brown, Xiaogang Zhang, Alexander Dawes, Javad Parvizi Md, Li Cao

Rothman Institute Papers

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty (THA). Traditional management typically involves full revision to ensure comprehensive infection eradication. However, for patients with well-fixed implants, partial revision in a single-stage cementless approach may provide a viable alternative, potentially preserving bone stock and reducing operative time. The relative efficacy of this approach compared with full revision remains to be fully explored. This multicenter study aims to determine whether partial revision in cementless single-stage exchange surgery offers comparable infection control outcomes to full revision for select patients with well-fixed implants.

METHODS: We conducted …

Race And Patient-Physician Communication On Blood Pressure Management: Helping Improve Care, Samar A. Nasser, Ashley Pender, Ayan Ali, Kardie Tobb, Keith C. Ferdinand

Division of Cardiology Faculty Papers

PURPOSE OF REVIEW: To provide an overview of the relationship of race and ethnicity and patient-physician/clinician communication on blood pressure management.

RECENT FINDINGS: The suboptimal interactions experienced by patients from underrepresented racial and ethnic populations may be improved by enriching relationships among clinicians, population health scientists, policymakers, and community members/leaders. Current care communication and policies for managing hypertension appear to be insufficient. Implementing and disseminating effective strategies to efficiently improve the quality of hypertension care and recognize social determinants of health among minoritized populations is intertwined with enhanced communication.

SUMMARY: Approaches such as self-affirmation—encouraging patients to reflect on their strengths …
